Crack both front windows. The low-pressure zone outside the windows will suck out the gas. Key note: Keep the back windows closed. "When all the windows are open, inside air doesn't exit, but is forced into the back," says Lou Bloomfield, Ph.D., a professor of physics at the University of Virginia.
